It was really interesting to read how your interest in modeling evolved into your interest in biology. However, the question is what are your academic interests, so mostly emphasize exactly that- your interest in biology, but you can still include modeling. Just make the connection more clear since there some wordiness and awkward similes.
Also, specify in your conclusion. NYU is basically asking why NYU? How will NYU fulfill your interest in biology because many other universities have resources for biological research.
My passion for modeling, like a flask, shaped my premature identity and molded me into an image that I believed fit me best.
I didn't understand why you used the simile until I read about your interest in biology. It seems that you wanted to show how you connected biology with modeling, but I felt that you made it clear in your second paragraph.
As I grew older and continued looking ahead, I realized that my undying thirst for this career would not quench my knowledge or sustain me for life. Intellectual interests always intertwine with careers and a career path that would thrust me into a world of negativity and judgment on the most flawless beings is not something that I intend to rush into.
These sentences sound awkward. It would sound coherent if you directly stated why you diverted from modeling to biology.
I traded being on the outside of the lens to become the person holding the camera, the microscope.
It would be interesting to have this sentence replace the first sentence of the second paragraph and then continue introducing why you took on biology.
like a picture. It's a bit like a puzzle
Stick with one comparison to clarify your point, and it is advised to not use the word "stuff" and "bit".
science defines us; defines our world, our universe
How?
Hopefully, my comments help! Reread it out loud to yourself. That will help! Good Luck!
